[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 2 The utility model provides a phospholipid film coating device, comprising:

[0022] A bottom plate 1, with an electrode substrate placed on top of the bottom plate 1;

[0023] The coating member is slidably arranged above the bottom plate 1, the contact surface between the coating member and the top of the electrode base is a smooth plane, and a coating pushing member is arranged at one end of the coating member, which is used to drive the coating member to slide on the surface of the electrode base.

[0024] The main function of the bottom plate 1 is to place the electrode base, so that the operator can drop the phospholipid solution on the electrode base; the main function of the coating member is to slide from the top surface of the electrode base to evenly apply the phospholipid solution on the surface of the electrode base to form a phospholipid film; the main function of the coating pusher is to push the coating member to slide on the surface of the electrode base. Overall, the utility model can effectively solve the defect of uneven coating caused by the needle flat coating of the phospholipid solution, and the structure is miniaturized, suitable for laboratory operation, and can simply and quickly achieve the effect of uniform thickness of the phospholipid film coating.

[0025] According to a further optimized solution, the film coating member includes a film coating plate 7, which is slidably arranged on the top of the electrode base. A slot 9 is provided on the top of the film coating plate 7, and the film coating pusher is arranged corresponding to the slot 9.

[0026] like Figure 1 As shown, the bottom surface of the coating plate 7 is a smooth surface, and its main function is to make the phospholipid solution dripped on the surface of the electrode substrate evenly cover the surface of the electrode substrate by sliding on the surface of the electrode substrate.

[0027] A further optimized solution is that the coating pushing member includes a pressing plate 3, one end of the pressing plate 3 is hinged on the base plate 1, the axis of the hinge shaft between the pressing plate 3 and the base plate 1 is arranged parallel to the coating plate 7, the middle part of the pressing plate 3 is hinged to one end of the supporting plate 5 through the second rotating shaft 6, the axis of the second rotating shaft 6 is arranged parallel to the coating plate 7, and the end of the supporting plate 5 away from the pressing plate 3 is arranged corresponding to the card slot 9.

[0028] According to a further optimized solution, a fixing seat 2 is fixedly connected to the top of the bottom plate 1 , and the pressing plate 3 is hinged on the fixing seat 2 through a first rotating shaft 4 , and the first rotating shaft 4 is arranged parallel to the coating plate 7 .

[0029] like Figure 1 and Figure 2 As shown, when in use, the operator presses down the free end of the pressing plate 3 to rotate the pressing plate 3 downward around the first rotating shaft 4. When the pressing plate 3 rotates, it pushes the supporting plate 5 forward through the second rotating shaft 6, and at the same time, a deflection is generated between the supporting plate 5 and the bottom plate 1, so that the supporting plate 5 pushes the coating plate 7 on the surface of the bottom plate 1 to move away from the first rotating shaft 4 through the card slot 9. After the electrode substrate is placed on the bottom plate 1 in advance and the phospholipid solution is dripped on its surface, the pressing plate 3 is pressed down to make the coating plate 7 slide over the surface of the electrode substrate, so that the phospholipid solution can be evenly and completely coated on the surface of the electrode substrate.

[0030] A further optimized solution is that a coating plate reset component is also provided on the base plate 1, and the coating plate reset component includes two groups of elastic ropes 12, one end of the two groups of elastic ropes 12 are respectively provided on the coating plate 7, and one end of the two groups of elastic ropes 12 are respectively located on both sides of the card slot 9, and the other ends of the two groups of elastic ropes 12 are respectively provided on the base plate 1, and the other ends of the two groups of elastic ropes 12 are respectively located on both sides of the fixing seat 2.

[0031] A further optimized solution is that the two ends of the top of the coating plate 7 are fixedly connected with a first fixing button 10, and the top of the base plate 1 is fixedly connected with a second fixing button 11. The two groups of second fixing buttons 11 are respectively located on both sides of the fixing seat 2, and the two ends of the elastic rope 12 are detachably connected to the first fixing button 10 and the second fixing button 11.

[0032] Elastic cord 12 can be selected from rubber bands or elastic cords. Figure 1 and Figure 2As shown, two sets of elastic ropes 12 are respectively and parallelly sleeved between two sets of first fixing buttons 10 and second fixing buttons 11. When the pressing plate 3 is pressed down to slide the film coating plate 7 forward to perform the film coating work, the two sets of elastic ropes 12 will be stretched as the film coating plate 7 moves forward. After the film coating is completed, the force of pressing the pressing plate 3 is slowly released, and the film coating plate 7 will slide in the opposite direction to the direction of the second fixing button 11 under the elastic force of the two sets of elastic ropes 12, so that the film coating plate 7 is reset. At the same time, it can be ensured that when sliding in the opposite direction, the film coating plate 7 is still in contact with the surface of the electrode substrate, and the phospholipid membrane on the surface of the electrode substrate is further coated.

[0033] According to a further optimized solution, a baffle plate 8 is fixedly connected to one side of the bottom plate 1 close to the coating plate 7 .

[0034] like Figure 1 and Figure 2 As shown, the main function of the baffle 8 is to block the electrode substrate when the coating plate 7 moves on the surface of the electrode substrate to coat the film, so as to ensure that the electrode substrate does not move.

[0035] The working process of this embodiment is as follows: the operator places the electrode substrate on the bottom plate 1, and makes one side of it close to the side of the baffle 8 close to the first rotating shaft 4, and drips an appropriate amount of phospholipid solution on the surface of the electrode substrate. After that, the coating plate 7 is placed on the end of the electrode substrate surface away from the baffle 8, and the pressing plate 3 is manually pressed down to make the coating plate 7 slide on the electrode substrate surface toward the baffle 8, and the phospholipid solution is evenly and completely applied to the surface of the electrode substrate. After that, the pressing plate 3 is slowly released, so that the coating plate 7 slides in the opposite direction on the surface of the electrode substrate under the rebound force of the two elastic ropes 12, so that the coating plate 7 is reset, and the electrode substrate is removed to obtain a well-prepared phospholipid dry film.
